Description

Technical Field

[0001] This application relates to the field of quartz sand conveying equipment, and in particular to quartz sand conveying pipelines for preventing blockage. Background Technology

[0002] In many industrial production processes, the transportation of quartz sand is a crucial step. Large quantities of quartz sand need to be transported from the raw material storage area to the processing stations via pipelines. Due to its inherent physical properties, quartz sand particles vary considerably in size. During transportation, smaller particles may fill the gaps between larger particles, gradually forming a dense aggregate as transport continues. Furthermore, when the moisture content of the quartz sand is high, the particles are prone to sticking together, forming agglomerates. These agglomerates may become stuck in the pipelines.

[0003] Furthermore, in some production scenarios where the continuity and stability of quartz sand transportation are extremely important, such as continuous production lines for high-end glass products, even a brief interruption in transportation caused by pipe blockage can lead to the scrapping of products being processed due to insufficient raw material supply, which greatly affects product quality and production efficiency.

[0004] Chinese patent application number 2024200890303 proposes a conveying device for quartz sand, including a conveying pipe and a base. One end of the conveying pipe is connected to a feed hopper, and the bottom of the conveying pipe away from the feed hopper is connected to a discharge pipe. The bottom of the discharge pipe is connected to a connecting ring via a corrugated pipe, and the top of the conveying pipe near the discharge pipe is connected to a steam hood. A rectangular hole communicating with the steam hood is provided inside the conveying pipe, and a filter screen that mates with the rectangular hole is detachably connected to the conveying pipe. A heating layer is provided between the inner and outer walls of the conveying pipe. In this invention, the conveying pipe can be stably adjusted at an angle via a hydraulic telescopic rod, and the connecting ring can be connected to the feed end of a quartz sand collection device or processing device. The corrugated pipe ensures stable communication between the discharge pipe and the connecting ring when the conveying pipe angle is adjusted, resulting in stable output of quartz sand. The auger conveyor can uniformly transport the quartz sand.

[0005] Regarding the aforementioned technologies, the inventors have discovered the following drawbacks: the aforementioned patents cannot unclog blocked quartz sand pipes. Utility Model Content

[0006] In order to reduce blockages when transporting quartz sand through pipelines and improve production efficiency, this application provides a quartz sand transport pipeline that prevents blockages.

[0007] The quartz sand conveying pipe for preventing blockage provided in this application adopts the following technical solution: it includes a conveying pipe, on which multiple inspection ports are provided and evenly spaced along the length of the conveying pipe. Each inspection port is provided with a detachable inspection plate. A retaining sleeve is provided on the outer wall of the conveying pipe. The retaining sleeve includes an upper shell and a lower shell fixed by bolts. A push rod is threadedly connected to the upper shell and the lower shell. An air pipe is provided on the upper shell. A positioning sleeve is provided on the outer wall of the air pipe. A positioning ring that cooperates with the positioning sleeve is provided on the upper shell. An air nozzle is provided at the end of the air pipe. A rubber ring is provided on the edge of the air nozzle. A compression mechanism for compressing the rubber ring is provided on the upper shell. It also includes an air pump connected to the air pipe.

[0008] Optionally, the positioning sleeve is provided with a positioning strip, the positioning ring is provided with a positioning groove that cooperates with the positioning strip, the positioning sleeve is provided with a positioning hole near the positioning strip, the positioning ring is provided with a through hole, and a positioning rod that cooperates with the positioning hole is slidably connected in the through hole.

[0009] Optionally, the upper and lower shells are provided with connecting ends for fixing, and the two ends of the upper and lower shells in the length direction are provided with threaded tubes, and the top rod is provided with threads that cooperate with the threaded tubes.

[0010] Optionally, the extrusion mechanism includes a fixed plate fixed to the inner wall of the upper shell, and an extrusion rod is provided on the fixed plate. There are multiple extrusion rods distributed in a rectangular ring. The extrusion rod is a telescopic rod with a hollow structure. An air bladder column is provided inside the extrusion rod, and the air bladder column is connected to an air pump through a pipeline.

[0011] Optionally, the compression rod includes a base rod connected to a fixed plate, an extension rod slidably connected to the base rod, and a top block provided at the end of the extension rod away from the base rod. When the extension rod compresses the rubber ring under the action of the airbag column, the top blocks will be arranged end to end to surround the outside of the air nozzle and seal the air nozzle.

[0012] In summary, this application includes the following beneficial technical effects:

[0013] 1. By evenly setting multiple inspection ports on the conveying pipe, operators can periodically open the inspection plates to visually check the conveying status of quartz sand inside the pipe and promptly detect potential blockages such as agglomeration and clumping. Once a blockage trend is detected, the air pump can be started immediately. Gas is ejected at high speed from the air nozzle through the air pipe. The powerful airflow can directly impact and break up the agglomerated quartz sand, restoring it to a loose state and allowing it to flow smoothly again, effectively preventing the blockage from worsening and ensuring the continuity of quartz sand conveying;

[0014] 2. The positioning sleeve of the air tube cooperates with the positioning ring of the upper shell, and the design of the positioning strip, positioning groove, positioning rod and other structures enables the air nozzle to accurately aim at the easily blocked parts inside the pipe, realize targeted air jet cleaning, and improve cleaning efficiency.

[0015] 3. The ferrule is connected by bolts to the upper and lower shells, which facilitates quick disassembly and installation. One end of the push rod can be moved to the outer wall of the pipe to make it easy to fix the ferrule to the outside of the pipe.

[0016] 4. The extrusion mechanism, in conjunction with a rubber ring, ensures a seal between the air nozzle and the delivery pipe during air jet cleaning, preventing gas leakage that could lead to poor cleaning results. The air bladder inside the extrusion rod allows the rod to extend according to the distance between the fixed plate and the outer wall of the pipe under the action of the air pump and pressure switch. The top block at the end of the extension rod is designed to provide a better sealing effect. Attached Figure Description

There are multiple security inspection ports, which are evenly spaced along the length direction of the conveying pipe 1. Removable security inspection plates are arranged on the security inspection ports, and sealing rings are adhesively bonded to the security inspection plates. A clamping sleeve is sleeved on the outer wall of the conveying pipe 1 along its length direction with the position of the security inspection port as the center line. The clamping sleeve includes an upper shell 2 and a lower shell 3 fixed by bolts. The upper shell 2 and the lower shell 3 cooperate to form an annular structure. Connecting ends 15 for bolts to pass through are arranged on both the upper shell 2 and the lower shell 3. At both ends of the upper shell 2 and the lower shell 3 in the length direction, there are screw pipes 16. The screw pipes 16 are located on the center line of the upper shell 2 and the lower shell 3, and the screw pipes 16 are perpendicular to both the upper shell 2 and the lower shell 3. The screw pipes 16 are of hollow cylindrical structure, and internal threads are arranged on the inner walls of the screw pipes 16. A top rod 4 that can move along the length direction of the screw pipe 16 is threadedly connected inside the screw pipe 16. An air pipe 5 is arranged on the upper shell 2. A positioning sleeve 6 is clamped on the outer wall of the air pipe 5. A positioning ring 7 used in cooperation with the positioning sleeve 6 is arranged at the center position of the upper shell 2. The positioning ring 7 is of hollow annular structure. The end of the air pipe 5 is communicated with a nozzle 8. A rubber ring 9 integrated with the nozzle 8 is arranged at one end of the nozzle 8 close to the air pipe 5. An extrusion mechanism for extruding the rubber ring 9 is arranged on the upper shell 2. It also includes an air pump communicated with the air pipe 5.

[0024] In one embodiment, according to the attached Figure 3 As shown in the figure, positioning strips 10 are arranged on the positioning sleeve 6 and are integrated with it. There are multiple positioning strips 10, which are symmetrically arranged about the center line of the positioning sleeve 6. The cross section of the positioning strip 10 is of "convex" shape structure. Positioning grooves 11 used in cooperation with the positioning strips 10 are arranged on the inner wall of the positioning ring 7. Positioning holes 12 are arranged on the positioning sleeve 6 near the positioning strips 10. There are multiple positioning holes 12, which are evenly spaced along the length direction of the positioning sleeve 6. A through hole 13 is arranged on the positioning ring 7. A positioning rod 14 used in cooperation with the positioning holes 12 is slidably connected inside the through hole 13.

[0025] In one embodiment, according to the attached Figure 1 and 3 As shown in the figure, the extrusion mechanism includes a fixing plate 17 fixed on the inner wall of the upper shell 2. Extrusion rods are fixed to the fixing plate 17 by screws. There are multiple extrusion rods, which are arranged in a rectangular ring shape. The heads and tails of each extrusion rod are connected in sequence and are arranged around the rectangle where the nozzle 8 is located. The extrusion rods are telescopic rods and are of hollow structure. An air bag column 18 is arranged inside the extrusion rods. The air bag column 18 is communicated with the air pump through a pipeline. The air pump and the pipeline are communicated through a pressure switch.

A long groove for the extension rod 20 to slide is arranged inside the bottom rod 19. A top block 21 is screwed to one end of the extension rod 20 away from the bottom rod 19. When the extension rod 20 extrudes the rubber ring 9 under the action of the air bag, each top block 21 will be arranged in sequence around the outside of the nozzle 8 and seal the nozzle 8.

[0026] The implementation principle of the quartz sand conveying pipe for preventing blockage in this application embodiment is as follows: The upper and lower shells are respectively wrapped around the outer wall of the conveying pipe at designated positions, so that the connecting ends of the upper and lower shells fit tightly. The bolts are tightened, and one end of the top rod is rotated to the position of the outer wall of the pipe to facilitate the fixing of the ferrule to the outside of the pipe. The positioning sleeve at one end of the air pipe is aligned with the positioning ring on the upper shell, so that the positioning strip slides in along the positioning groove. Then, the positioning rod is inserted into the through hole and inserted into the positioning hole to complete the fixed installation of the air pipe. At this time, the air nozzle is accurately facing the part of the inner wall of the conveying pipe that needs to be air-cleaned. The air pump works, and the gas enters the airbag column through the pressure switch, which causes the squeezing rod to extend. Multiple squeezing rods distributed in a rectangular ring shape drive the top block to evenly squeeze the rubber ring. Air is supplied to the air nozzle. The powerful airflow can effectively break up the clumps and restore them to a loose state.

[0027] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
